Unable to add shared library details under unclassified section using latest jenkins chart

[vsyamala1]

Describe the bug

We want to add our global shared library section in our jenkins value file and we are following below document: https://github.com/jenkinsci/helm-charts/blob/main/charts/jenkins/README.md#breaking-out-large-config-as-code-scripts

jenkins:
controller:
JCasC:
configScripts:
unclassifiedCasc: |
unclassified:

Here is the error we are getting:

20624 warnings.go:70] Use tokens from the TokenRequest API or manually created secret-based tokens instead of auto-generated secret-based tokens.
Error: UPGRADE FAILED: failed to create resource: ConfigMap "jenkins-test1-jenkins-config-unclassifiedCasc" is invalid: metadata.name: Invalid value: "jenkins-test1-jenkins-config-unclassifiedCasc": a lowercase RFC 1123 subdomain must consist of lower case alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character (e.g. 'example.com', regex used for validation is 'a-z0-9?(.a-z0-9?)*')

Version of Helm and Kubernetes

- Helm: v3.17.2
- Kubernetes: v1.28.11+vmware.2

Chart version

What happened?

1.Add the shared library section in jenkins values file using https://github.com/jenkinsci/helm-charts/blob/main/charts/jenkins/README.md#breaking-out-large-config-as-code-scripts 

jenkins:
  controller:
    JCasC:
      configScripts:
        unclassifiedCasc: |
          unclassified:


2. Deploy the jenkins chart and you will see this error
 20624 warnings.go:70] Use tokens from the TokenRequest API or manually created secret-based tokens instead of auto-generated secret-based tokens.
Error: UPGRADE FAILED: failed to create resource: ConfigMap "jenkins-test1-jenkins-config-unclassifiedCasc" is invalid: metadata.name: Invalid value: "jenkins-test1-jenkins-config-unclassifiedCasc": a lowercase RFC 1123 subdomain must consist of lower case alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character (e.g. 'example.com', regex used for validation is '[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*')

What you expected to happen?

Shared-Library should reflect in Jenkins-UI

How to reproduce it

Anything else we need to know?

No response

It seems like as the error states, it expects the CM name "jenkins-test1-jenkins-config-unclassifiedCasc" to "consist of lower case alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character". If you remove the uppercase letter by changing, say, unclassifiedCasc to unclassified-casc, do you receive the same error?

that solution worked, please update the documentation as well.
